Polidoro BR, de Oliveira MJK, Braga FDSC, Polycarpo GDV. Mannan oligosaccharide as an alternative to infeed antibiotics to improve growth performance of broilers: a meta-analysis. Br Poult Sci 2024:1-9. [PMID: 39212222 DOI: 10.1080/00071668.2024.2391764] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2024] [Accepted: 06/17/2024] [Indexed: 09/04/2024]
Abstract
1. The purpose of this meta-analysis was to evaluate the effect of mannan oligosaccharide (MOS) as an alternative to antibiotic growth promoters (AGP) on feed intake (FI), body weight gain (BWG), and feed conversion ratio (FCR) of broilers.2. Data from 75,594 broilers were extracted from 17 articles (19 trials) published between January 2010 and March 2023. The main criteria for the publication selection were as follows, at least three treatments applied (negative control group without MOS or AGP versus MOS or AGP supplementation), presence of performance results, and intra-experimental variation associated with the mean of response (such as standard error). Treatments were classified as control, MOS, or AGP, and adjusted means of treatment were compared. Additionally, the average daily gain (ADG) and average daily feed intake (ADFI) of each type of supplementation were calculated relative (Δ) to the control group (ΔADFI and ΔADG) and expressed as a percentage of the difference.3. Broilers receiving a diet supplemented with MOS had a 3.7% better BWG and 3% better FCR compared to the control diet (P < 0.001), but these variables were similar to the group receiving AGP supplementation. No significant difference was detected in FI among treatments (P > 0.050). The relationship between ΔADG and ΔADFI was linear for the MOS and AGP-supplemented group (P < 0.050). The ΔADG of broilers fed diets supplemented with MOS or AGP was 6.4% and 4.54% when ΔADFI was zero, respectively. The ΔADG of MOS increased by 0.58% for every 1% of increasing observed in ΔADFI. The corresponding value for the increased ΔADG for the AGP group was 0.69%.4. The results of this meta-analysis indicated that MOS supplementation is effective in increasing BWG and reducing FCR, similar to broilers fed a diet supplemented with AGP. Therefore, MOS is a safe and sustainable alternative for AGP-free poultry production.

Abstract
Bioactive peptides (BPs) are protein fragments with beneficial effects on metabolism, physiology, and diseases. This review focuses on proteolytic BPs, which are produced by the action of gut microbiota on proteins in food and have demonstrated to influence the composition of gut microbes. And gut microbiota are candidate targets of BPs to alleviate oxidative stress, enhance immunity, and control diseases, including diabetes, hypertension, obesity, cancer, and immune and neurodegenerative diseases. Despite promising results, further research is needed to understand the mechanisms underlying the interactions between BPs and gut microbes, and to identify and screen more BPs for industrial applications. Overall, BPs offer potential as therapeutic agents for various diseases through their interactions with gut microbes, highlighting the importance of continued research in this area.

Abstract
This experiment was carried out to investigate the effect of bioactive peptides derived from casein on performance, nutrient digestibility, enzyme activity and intestinal microbial population in broiler chickens. In this study, 350 1-day-old male Ross 308 broiler chicks were distributed among 35 pens in a completely randomized design with seven treatments, five replicates and 10 chicks in each replicate. The experimental treatments included: basal diet without any additives (control), basal diet + Avilamycin antibiotic, basal diet + 200, 400, 600, 800 and 1000 mg of peptides per kg of diet. Results showed no significant effects of the experimental treatments on weight gain and feed conversion ratio during the starter period, but there was a significant improvement in weight gain in grower, finisher and whole periods in chicks fed with diet containing 1000 mg/kg peptides (p < 0.05). Adding peptides improved intestinal morphology (in duodenum and ileum) (p < 0.05). Supplementation of casein peptides significantly reduced thiobarbituric acid reactive substances concentration in breast and thigh meat. The activity of amylase, lipase and protease enzymes improved in treatments containing 800 and 1000 mg peptides in comparison to the control treatment. The use of casein-peptides increased intestinal Lactobacillus and decreased Coliform populations.

Abstract
Recently, it is necessary to formulate high-quality, balanced and low-cost rations for ruminants from nontraditional sources. The present study conducted to investigate the impact of partially replacing corticated cottonseed (CS) cake with sesame meal (SM) in a lamb feedlot diet on growth performance, nutrient digestion, rumen fermentation and blood biochemistry. Fifteen growing lambs with an initial body weight of 27.4 ± 1.2 kg (6-7 months old) were randomly assigned into three equal groups (n = 5). Lambs in control group (CS) fed a basal diet, while 8% and 16% SM were used to replace an equal portion of corticated CS cake in the second (8SM) and third (16SM) groups respectively. Results showed that most parameters of growth performance and nutrient digestibility were significantly improved (p < 0.05) with the partial replacement of SM (8SM and/or 16SM). Regarding ruminal parameters, ruminal pH and total volatile fatty acids concentration increased (p < 0.05), while ammonia level and total protozoa count decreased with the partial replacement of SM. Moreover, blood parameters showed variant responses to SM partial replacement. Total protein increased, and glucose decreased significantly with 16SM, while cholesterol showed a significant decreasing with both SM replacement levels. SM may substitute CS cake in lamb diet without detrimental effects on performance, digestibility and ruminal fermentation.

[PMID: 37402448 PMCID: PMC10623036 DOI: 10.5713/ab.23.0091] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2023] [Revised: 05/13/2023] [Accepted: 06/14/2023] [Indexed: 07/06/2023] Open
Abstract
OBJECTIVE The objective of this study was to investigate the effect of supplementation with enzymolytic soybean meal (ESBM) on broilers fed low crude protein (CP) diets. METHODS A total of 360 one-day-old broilers were randomly assigned to six treatments with 6 replicates per treatment and 10 chicks per replicate for a period of 42 days. Chicks were fed a basal standard high-CP diet as a positive control (PC), a low-CP diet (reducing 10 g/kg CP from the PC) as a negative control (NC), or an NC + 0.5%, 1.0%, 1.5%, or 2.0% ESBM diet. RESULTS Compared to chicks fed the PC, chicks fed the NC had a decreased body weight gain (BWG, p<0.05) from 1 to 42 days, but supplementation with 2.0% ESBM restored BWG (p<0.05) and even linearly improved the feed conversion rate (FCR, p<0.05). Digestibility of CP and ether extract was increased (p<0.05) in chicks fed a 1.0% ESBM diet compared to the PC. With increasing levels of ESBM, nitrogen (N) excretion decreased (p<0.05). The addition of ESBM to the diet did not affect (p>0.05) serum concentrations of total protein, albumin and total cholesterol but led to a descending trend in triglycerides and an ascending trend in calcium and urea N at 42 days (p<0.10). There were no differences (p>0.05) in villus height (VH), crypt depth (CD), and VH/CD (V/C) of the duodenum and jejunum between the PC and NC at both 21 days and 42 days, while increasing dietary ESBM levels linearly (p<0.05) decreased CD and increased V/C of the duodenum and jejunum at both 21 days and 42 days. CONCLUSION The findings indicated that ESBM could be used in broiler low-CP diets to improve production performance, decrease N excretion, and enhance intestinal health.

Orally delivered Bacillus subtilis expressing chicken NK-2 peptide stabilizes gut microbiota and enhances intestinal health and local immunity in coccidiosis-infected broiler chickens. Poult Sci 2023; 102:102590. [PMID: 36940653 PMCID: PMC10033313 DOI: 10.1016/j.psj.2023.102590] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2022] [Revised: 02/09/2023] [Accepted: 02/09/2023] [Indexed: 02/17/2023] Open
Abstract
We recently reported a stable Bacillus subtilis-carrying chicken NK-lysin peptide (B. subtilis-cNK-2) as an effective oral delivery system of an antimicrobial peptide to the gut with therapeutic effect against Eimeria parasites in broiler chickens. To further investigate the effects of a higher dose of an oral B. subtilis-cNK-2 treatment on coccidiosis, intestinal health, and gut microbiota composition, 100 (14-day-old) broiler chickens were allocated into 4 treatment groups in a randomized design: 1) uninfected control (CON), 2) infected control without B. subtilis (NC), 3) B. subtilis with empty vector (EV), and 4) B. subtilis with cNK-2 (NK). All chickens, except the CON group, were infected with 5,000 sporulated Eimeria acervulina (E. acervulina) oocysts on d 15. Chickens given B. subtilis (EV and NK) were orally gavaged (1 × 1012 cfu/mL) daily from d 14 to 18. Growth performances were measured on d 6, 9, and 13 postinfection (dpi). Spleen and duodenal samples were collected on 6 dpi to assess the gut microbiota, and gene expressions of gut integrity and local inflammation makers. Fecal samples were collected from 6 to 9 dpi to enumerate oocyst shedding. Blood samples were collected on 13 dpi to measure the serum 3-1E antibody levels. Chickens in the NK group showed significantly improved (P < 0.05) growth performance, gut integrity, reduced fecal oocyst shedding and mucosal immunity compared to NC. Interestingly, there was a distinct shift in the gut microbiota profile in the NK group compared to that of NC and EV chickens. Upon challenge with E. acervulina, the percentage of Firmicutes was reduced and that of Cyanobacteria increased. In NK chickens, however, the ratio between Firmicutes and Cyanobacteria was not affected and was similar to that of CON chickens. Taken together, NK treatment restored dysbiosis incurred by E. acervulina infection and showed the general protective effects of orally delivered B. subtilis-cNK-2 on coccidiosis infection. This includes reduction of fecal oocyst shedding, enhancement of local protective immunity, and maintenance of gut microbiota homeostasis in broiler chickens.

Abstract
The objective of the current study was to investigate the influence of sesame meal bioactive peptides (SMBP) individually or in combination with a mixture of savory (Satureja khuzestanica) and thyme (Thymus daenensis) essential oils (STEO) on growth performance, carcass, jejunal morphology, and cecal microbial composition of broiler chickens. A total number of 250-day-old male Ross broiler chicks were randomly allocated to 5 dietary treatments with 5 replicates per each. Dietary treatments were a corn-soybean meal diet as control; control diet supplemented with 0.5 g/kg of Bacitracin as antibiotic (A); 3 g/kg of SMBP; 0.5 g/kg of STEO; and a combination of 3 g/kg of SMBP and 0.5 g/kg of STEO. Results indicated that inclusion of SMBP + STEO in diet improved body weight gain and feed conversion ratio during 11 to 24 days (P < 0.05). Dietary treatments had no significant effect on the carcass characteristics and internal organs. In jejunal morphology, the villus length (VL) and the ratio of VL to crypt depth (CD) were greater in birds which received SMBP + STEO diets, while CD was lower in broilers fed with SMBP + STEO diet (P < 0.05). Inclusion of SMBP in combination with STEO increased viable count of Lactobacillus while the population of E. coli decreased in birds fed with SMBP + STEO diet (P < 0.05). According to the results of this experiment, it can be concluded that dietary SMBP in combination with STEO had positive effects on the growth performance, jejunal morphometric indices, and cecal microbial composition of broiler chickens.

Abstract
The growing period is a critical period for growth and development in laying hens. During this period, chicks grow rapidly, but are accompanied by unstable digestive function, incomplete organ development, and high mortality. Small peptide, a feed additive, which has been proved to promote intestinal development and immunity in poultry. In order to elucidate the effects of small peptides on growth performance, immunity, antioxidant capacity, and intestinal health of growing laying hens, a total of 900 Tianfu green shell laying hens (1-day-old) were randomly divided into 5 treatments with 6 replicates of 30 birds each in this 18-week trial. Dietary treatments included a corn-soybean meal-based diet supplemented with 0 g/kg, 1.5 g/kg, 3.0 g/kg, 4.5 g/kg and 6.0 g/kg small peptide, respectively. The results showed that the supplementation of small peptides significantly increased growth rate (P<0.05) in laying hens, as well as elevated the serum immunoglobulins (P<0.05) and antioxidant indices (P<0.05), however, it decreased inflammation parameters (P<0.05). The supplementation of small peptides enhanced the intestinal function by promoting gut development (P<0.05) and improving gut integrity (P<0.05), barrier function (P<0.05) and the diversity of gut microbiota (P<0.05) in the growing hens. The best performance was recorded among the hens fed 4.5 g/kg level of small peptide. Taken together, these results showed that small peptide supplementation could improve the economic value of growing hens by promoting growth rate, disease resistance, and the optimal amount of addition for Tianfu green shell laying hens was 4.5 g/kg.

Front Vet Sci 2022; 9:889485. [PMID: 35812843 PMCID: PMC9267357 DOI: 10.3389/fvets.2022.889485] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2022] [Accepted: 05/04/2022] [Indexed: 11/13/2022] Open
Abstract
In order to reduce the negative effects caused by oxidative stress on broilers, it is particularly important to find ways to alleviate oxidative stress. As a natural plant extract, L-theanine has a variety of biological effects, such as improving antioxidant capacity, promoting growth, and enhancing immunity and antitumor. This trial evaluated the effects of dietary supplementation of L-theanine on growth performance, antioxidation, meat quality, and intestinal microflora in 817 White Feather Broilers. A total of 108 21-day-old 817 broilers with similar body weight (BW) were randomly divided into three groups with six replicates per group and six chickens within each replicate. The three groups were corn-soybean-based diet (NC group); basal diet plus drinking water with 30 mg hydrocortisone/kg (PC group); and basal diet supplemented with 400 mg L-theanine/kg plus drinking water with 30 mg hydrocortisone/kg (LT group). Compared with the NC group, from 21 to 24 days of age, the PC and LT groups had decreased BW, average daily gain (ADG), and average daily feed intake (ADFI), and increased feed to gain ratio (F/G; p < 0.05). At 24 days of age, the LT group had improved superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities in serum as compared to the NC group (p < 0.05). The LT group broilers also had significantly higher concentrations of malondialdehyde (MDA) in serum and liver (p < 0.05). On the 42nd days, the PC group had lower PH45min (p < 0.05) than the NC and LT groups and higher cooking loss and shear force (p < 0.05). Moreover, the villi height of the PC group was significantly lower in jejunum than the NC group (p < 0.05). The LT group had a higher ZO-1 content in duodenum than the NC and PC groups (p < 0.05). The activity of GSH-Px in the liver of the LT group was increased than in the PC group (p < 0.05). The relative abundance of Firmicutes in the LT group was significantly higher than in the NC and PC groups (p < 0.05). These results suggested that the effects of acute oxidative stress on growth performance and meat quality of broilers are continuous, and dietary supplementation of L-theanine could improve the growth performance and meat quality, enhance the intestinal mucosal barrier and antioxidant capacity, and improve the composition of the intestinal flora of broilers caused by acute oxidative stress.

Abstract
The objective of this study was to investigate the effects of soybean meal (SBM) treated with acetic or citric acids on growth performance, microbial population, digestive enzyme activities, nutrient digestibility, and jejunal morphology in broiler chickens. A total of 350 one-day-old male broiler chicks (Ross 308) were randomly distributed into 7 experimental groups with 5 replicates per each. Experimental treatments were diets containing untreated SBM (control) and SBM treated with two acid sources and their concentrations including 5, 10, and 15% acetic acid (A1, A2, and A3) or 0.25, 0.50, and 0.75% citric acid (C1, C2, and C3). Results showed that trypsin inhibitors and lectins as the main SBM anti-nutrients significantly reduced in acid-treated SBM compared with untreated SBM (P < 0.05). During 1-24 days, body weight gain increased in chicks fed the C2 diet (P < 0.05). Feeding of the C2 diet increased feed intake compared with A1, A2, and C3 groups (P < 0.05). Feed conversion ratio improved in chicks fed with C2, C3, and A2 diets compared with the control group (P < 0.05). The greatest villus length, villus length to crypt depth ratio, and villus surface area were observed in the C2 diet (P < 0.05). A significant increase in protease and lipase activity was found in broilers which received a C2 diet compared with the control group (P < 0.05). Broiler chickens fed with the C2 diet had a higher organic matter and crude protein digestibility than the chicks which received the control diet (P < 0.05) and dry matter digestibility was the lowest in broilers fed with the A3 diet (P < 0.05). In conclusion, the acid hydrolyzing process had a beneficial effect on the nutritional value of SBM. In addition, data showed that acid-hydrolyzed SBM had the potential to exert positive influences on growth performance, jejunal morphology, and nutrient utilization in broiler chickens.

Anim Sci J 2022; 93:e13781. [PMID: 36437240 DOI: 10.1111/asj.13781] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2022] [Revised: 08/27/2022] [Accepted: 10/24/2022] [Indexed: 11/29/2022]
Abstract
This study investigated the effects of bioactive peptides derived from solid-state fermentation of cottonseed meal on the growth performance, apparent dietary digestibility, serum biochemical parameters, protein metabolism, antioxidant activity, and immunity in yellow-feathered broilers. A total of two hundred forty 21-days-old male broilers were randomly divided into four groups with six replicates per group. The control group received a basal diet and three experimental groups were fed diets with 1%, 2%, and 3% cottonseed meal bioactive peptides (CSBP) replacing equivalent protein of cottonseed meal in basic diet. Dietary supplementation of 2% and 3% CSBP increased the average daily weight gain, crude protein digestibility, total serum protein, and immunoglobulin (Ig) G contents in serum (P < 0.05). The 3% CSBP increased albumin, total antioxidant capacity, spleen weight/bodyweight, interleukin-6, and IgM, while reducing the feed to gain ratio, total cholesterol, urea nitrogen, total superoxide dismutase, glutathione peroxidase, and malondialdehyde contents in serum (P < 0.05). The 2% CSBP diet increased PepT1 expression in duodenum, jejunum, and ileum (P < 0.05). The 1%, 2%, and 3% CSBP diets increased S6kinase-polypeptide-1 and inositol-3-hydroxylase expression in chest and leg muscles (P < 0.05). The CSBP addition in diets can improve growth performance, nutrient digestibility, protein metabolism, antioxidant, and immune capabilities of yellow-feathered broilers.

Abstract
Antibiotics use in poultry as a growth promoter leads to the propagation of antibiotic-resistant microorganisms and incorporation of drug residues in foods; therefore, it has been restricted in different countries. There is a global trend to limit the use of antibiotics in the animal products. Prevention of the antibiotics use in the poultry diets led to the reduction in the growth performance. Consequently, there is a high demand for natural substances that lead to the same growth enhancement and beneficially affect poultry health. These constituents play essential roles in regulating the normal physiological functions of animals including the protection from infectious ailments. Nutraceuticals administration resulted beneficial in both infectious and noninfectious diseases. Being the natural components of diet, they are compatible with it and do not pose risks associated with antibiotics or other drugs. Nutraceuticals are categorized as commercial additives obtained from natural products as an alternative feed supplement for the improvement of animal welfare. This group includes enzymes, synbiotics, phytobiotics, organic acids and polyunsaturated fatty acids. In the present review, the summary of various bioactive ingredients that act as nutraceuticals and their mode of action in growth promotion and elevation of the immune system has been presented.
